CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, and __devexit
from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

"pvt->ambase" is a u64 datatype. The intent here is to fill the first
half in the first call to pci_read_config_dword() and the other half in
the second. Unfortunately the pointer math is wrong so we set the wrong
data.

In order to avoid loosing error events, it is desirable to group
error events together and generate a single trace for several identical
errors.
The trace API already allows reporting multiple errors. Change the
handle_error function to also allow that.
The changes at the drivers were made by this small script:
$file .=$_ while (<>);
$file =~ s/(edac_mc_handle_error)\s*\(([^\,]+)\,([^\,]+)\,/$1($2,$3, 1,/g;
print $file;

Remove the arch-dependent parameter, as it were not used,
as the MCE tracepoint weren't implemented. It probably doesn't
make sense to have an MCE-specific tracepoint, as this will
cost more bytes at the tracepoint, and tracepoint is not free.
The changes at the EDAC drivers were done by this small perl script:
$file .=$_ while (<>);
$file =~ s/(edac_mc_handle_error)\s*\(([^\;]+)\,([^\,\)]+)\s*\)/$1($2)/g;
print $file;

The debug macro already adds that. Most of the work here was
made by this small script:
$f .=$_ while (<>);
$f =~ s/(debugf[0-9]\s*\(\s*)__FILE__\s*": /\1"/g;
$f =~ s/(debugf[0-9]\s*\(\s*)__FILE__\s*/\1/g;
$f =~ s/(debugf[0-9]\s*\(\s*)__FILE__\s*"MC: /\1"/g;
$f =~ s/(debugf[0-9]\s*\(\")\%s[\:\,\(\)]*\s*([^\"]*\s*[^\)]+)__func__\s*\,\s*/\1\2/g;
$f =~ s/(debugf[0-9]\s*\(\")\%s[\:\,\(\)]*\s*([^\"]*\s*[^\)]+),\s*__func__\s*\)/\1\2)/g;
$f =~ s/(debugf[0-9]\s*\(\"MC\:\s*)\%s[\:\,\(\)]*\s*([^\"]*\s*[^\)]+)__func__\s*\,\s*/\1\2/g;
$f =~ s/(debugf[0-9]\s*\(\"MC\:\s*)\%s[\:\,\(\)]*\s*([^\"]*\s*[^\)]+),\s*__func__\s*\)/\1\2)/g;
$f =~ s/\"MC\: \\n\"/"MC:\\n"/g;
print $f;
After running the script, manual cleanups were done to fix it the remaining
places.
While here, removed the __LINE__ on most places, as it doesn't actually give
useful info on most places.

Kernel kobjects have rigid rules: each container object should be
dynamically allocated, and can't be allocated into a single kmalloc.
EDAC never obeyed this rule: it has a single malloc function that
allocates all needed data into a single kzalloc.
As this is not accepted anymore, change the allocation schema of the
EDAC *_info structs to enforce this Kernel standard.

As EDAC doesn't use struct device itself, it created a parent dev
pointer called as "pdev". Now that we'll be converting it to use
struct device, instead of struct devsys, this needs to be fixed.

The number of pages is a dimm property. Move it to the dimm struct.
After this change, it is possible to add sysfs nodes for the DIMM's that
will properly represent the DIMM stick properties, including its size.
A TODO fix here is to properly represent dual-rank/quad-rank DIMMs when
the memory controller represents the memory via chip select rows.

Almost all edac drivers initialize csrow_info->first_page,
csrow_info->last_page and csrow_info->page_mask. Those vars are
used inside the EDAC core, in order to calculate the csrow affected
by an error, by using the routine edac_mc_find_csrow_by_page().
However, very few drivers actually use it:
e752x_edac.c
e7xxx_edac.c
i3000_edac.c
i82443bxgx_edac.c
i82860_edac.c
i82875p_edac.c
i82975x_edac.c
r82600_edac.c
There also a few other drivers that have their own calculus
formula internally using those vars.
All the others are just wasting time by initializing those
data.
While initializing data without using them won't cause any troubles, as
those information is stored at the wrong place (at csrows structure), it
is better to remove what is unused, in order to simplify the next patch.

On systems based on chip select rows, all channels need to use memories
with the same properties, otherwise the memories on channels A and B
won't be recognized.
However, such assumption is not true for all types of memory
controllers.
Controllers for FB-DIMM's don't have such requirements.
Also, modern Intel controllers seem to be capable of handling such
differences.
So, we need to get rid of storing the DIMM information into a per-csrow
data, storing it, instead at the right place.
The first step is to move grain, mtype, dtype and edac_mode to the
per-dimm struct.

When i5400_edac driver is removed and re-loaded a few times, it causes
an OOPS, as it is currently decrementing some PCI device usage two
times.
When called inside a loop, pci_get_device() will call
pci_put_device(). That mangles the error count. In this specific
case, it seems easier to just duplicate the call.
Also fixes the error logic when pci_get_device fails.

These const tables are currently marked __devinitdata, but
Documentation/PCI/pci.txt says:
"o The ID table array should be marked __devinitconst; this is done
automatically if the table is declared with DEFINE_PCI_DEVICE_TABLE()."
So use DEFINE_PCI_DEVICE_TABLE(x).

The i5400 EDAC driver has several bugs with chip-select row computation
which most likely lead to bugs in detailed error reporting. Attempts to
contact the authors have gone mostly unanswered so I am presenting my diff
here. I do not subscribe to lkml and would appreciate being kept in the
cc.
The most egregious problem was miscalculating the addresses of MTR
registers after register 0 by assuming they are 32bit rather than 16.
This caused the driver to miss half of the memories. Most motherboards
tend to have only 8 dimm slots and not 16, so this may not have been
noticed before.
Further, the row calculations multiplied the number of dimms several
times, ultimately ending up with a maximum row of 32. The chipset only
supports 4 dimms in each of 4 channels, so csrow could not be higher than
4 unless you use a row per-rank with dual-rank dimms. I opted to
eliminate this behavior as it is confusing to the user and the error
reporting works by slot and not rank. This gives a much clearer view of
memory by slot and channel in /sys.
